Nothing that I've set up. I do have AV and I'm sure there is a firewall included in my service.
I have the weirdest things happen with discord for instance. I can be on it (browser app) on minute, turn around and it's gone, black screen with their wumpus doohicky.
I can go to FireFox and get there, or I can USUALLY go to the desktop app, but after a few moments the browser app (Chrome) will be back up.
I always have about this many tabs open and NOT ONE OTHER SITE is affected. Not one, only discord.
Then it comes back.
Clearing cache (not cookies) nor clearing cookies has any effect on the issue
